To all whom itjnecey concern:

Be it known that we, OHARL s Donns and JOHN R. PITMAN, citizens of theUnited States,

residin at Haskell, county of Bassaic, and State 0 New Jersey, haveinvented anew and useful Improvement in Machines for Makin Comb-Powder,of which the following is a 1, clear, and exact description, referencebeing had to the accompanying drawings, which form a part of thisspecification.

Our invention has for its object the production of a machine by the useof which comb-powder may be formed.

We will first describethe embodiment of our invention as illustrated theaccompanying drawings andthen point out the invention in the claims.

In the drawings, Figure 1 is a'p'lan View of the machine. Fig. 2 isaside elevation thereof. Fig. 3 is an end elevation. Fig. 4 is alongitudinal sectional view on the line 4 4, Fig. 3. Fig. 5 is across-section through the central cutter on the line 5 5, Fig. 3. Fig. 6is a plan view of a modified form of bed. Fig. 7 is a sectional viewthereof. Fi 8 is a view showing a block or plate 0 comb-powder. Fig. 9is a view showing a double block or plate of comb-powder, and Fig. 10 isan elevation of a modified form of cutting-roll.

A is the base, upon which is secured or formed the bed B and also theracks C C.

D is a shaft having crank D. To this shaft D are secured the pinions EE, one of each meshing with a correspondin rack. Secured upon this shaftD is the roll F, which is a double roll to form the double comb-plate,as shown in Fig. 9. The roll F is therefore essentially a double roll,having at one end of each roll angular cutting edges f from which extendlongitudinal cutting edges f e uispaced around the periphery of the rolla istance apart equal to the desired distance between comb-prongs. Atthe end of these longitudinal cutting edges opposite the angular cuttingedges is formed a cut-away portion or pocket f which pocket is quiteadvantageous for removal of the cut powder. Beyond this pocket is theplain surface f 3 in a lower plane than the cuttin edges f. At the outerend of this surface 3 is the circular cuttin edge f which cutting edgeis in the same p ane as the cutting edge f In case onlyaQngIe-cmbpowderiiI gih or strip 1s to be made we use the-roll as is secured tothe base A.

The block or strip of powder to be formed into comb-powder is placed uon the bed B and the roll F passed over it by turning the crank, theproper pressure being obtained by means of the screws H.

Instead of formin the cutting edges on the roll F we can use a pain-faced roller, as shown in Fig-Land place the cutting edges, cutawayportion, and lower plain surface, which in Fig. 1 is upon the roller,upon the bed B, as also shown in Fig. 7.

When we place the cutting edges upon the roller, we prefer to usespring-fingers L, which lie or rest upon the roll between thelongitudinal cutting edges f this to hold the powder from hugging too 0osely to the roll.

We do not in this application claim, broadiy the cuttin device or thecutting-roll here l wn and escribed, as wehave illustrated d ascribed,and claimed such a cutting device and cutting-roll in an applicationcontemporaneously filed by us with this application and bearin filingdate of June 28, 1905, and being seriall y numbered 267,328.

Having now fully described our invention, What we claim, and desire toprotect by Letters Patent, is

1. In a machine for forming comb-powder, in combination, a bed-plateadapted to receive the owder block or strip and a roller, one of saidevices havin angular cutting edges formin one end an straight cuttingedges extending therefrom, a cut-away ortion or pocket beyond strai htcutting e ges, and means to cause said ro ler to rotate and travel oversaid bed-plate.
